Many Kuiper Belt Object and asteroids have now been discovered to be part of more complex dynamical systems consisting of a primary and its satellites. In this case, the primary's motion is not strictly keplerian around the Sun since the influence of its companions disturbs its trajectory. We present a model which will allow for a global solution when fitting the orbital parameters to astrometric observations. The goal of this work is to be able to constrain the masses and other dynamical parameters in this kind of system. The multiple system which has been studied for the longest time and would then make a perfect candidate is Pluto's one, with its binary Pluto/Charon and its smaller satellites. Our model has been tested on simulated observations of Pluto's system in order to determine the parameters which can be properly determined.
